类 EntranceNode

java.lang.Object

com.alibaba.csp.sentinel.node.StatisticNode

com.alibaba.csp.sentinel.node.DefaultNode

com.alibaba.csp.sentinel.node.EntranceNode

所有已实现的接口:

Node, OccupySupport, DebugSupport

public class EntranceNode
extends DefaultNode

A Node represents the entrance of the invocation tree.

One Context will related to a EntranceNode, which represents the entrance of the invocation tree. New EntranceNode will be created if current context does't have one. Note that same context name will share same EntranceNode globally.
